Three-point internal micrometer MS908.664 — self-centring design, 125–150 mm (Metav IndustryLine)
The Three-point internal micrometer MS908.664 is a precision instrument for accurate measurement of blind bores and internal diameters in machine shops and inspection benches
- Self-centring three-point contact
- Accuracy ±0.005 mm
- Hardened measuring faces
- Supplied in protective case
Consistent concentric measurement where it matters
The instrument’s self-centring three-point contact mechanism converts small radial differences into a single, centred datum, ensuring high repeatability during blind-bore checks. With a mechanical resolution and accuracy of ±0.005 mm, the device supports tight tolerance verification and process control for internal diameters. This level of precision is particularly useful when comparing series parts or validating internal fits, as the three-point geometry minimises eccentricity and reduces operator-induced variation.
Robust construction for repetitive workshop use
A durable construction and hardened measuring faces protect the contact points from wear and maintain measurement integrity over prolonged use. The analogue, mechanical drive reduces complexity and avoids battery dependence, making the tool suitable for routine quality inspections on the shop floor. The overall length of 145 mm gives the reach required for its measurement range while keeping the instrument compact enough for stable handling during repeated checks.
Ideal balance of reach and stiffness for standard applications
Classified in the standard range for internal measurement instruments (125–150 mm), this micrometer offers the best compromise between measuring reach and structural rigidity. That balance is critical in metalworking and fixture assembly, where longer tools can introduce deflection and shorter tools lack coverage. The design is optimised for blind bores, providing reliable access and reproducible contact even when full through-access is not available.
Delivered protected and ready for transport
The instrument is supplied in a protective case to safeguard measuring faces and the mechanism during transport and storage. Built for regular inspection cycles, it integrates easily into workshop tool sets and measurement benches; its analogue readout is simple to interpret and maintain, supporting efficient quality routines without complex electronic calibration procedures.
